PACKER FOR ENVELOPS, CARDS, OR THE LIKE.

T all whom it may concern:

Be it known that I, Sinner L. Lone, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and rially from some machine, as, for example,

an envelop sealing or stamping machine, a printing press, etc.

It is the object of my invention to provide improved and highly efficient means for receiving each said envelop or card as it is delivered from the sealing machine and to move the same out of the plane of delivery and place it in a stack of such envelops or cards. In so packing and stacking envelops or cards, it is essential that the envelop shall be held in its upright position as it is moved to the stack and that the envelope already in the stack, together with the one just placed there, shall be restrained from return movement after each envelop has been positioned. My invention provides a novel finger controlled in operation by the movement of the envelop being delivered to,

the stack for efiecting this function.

My invention also comprises novel and simple features of construction in relation to the guides, receiving table and back rest.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims.

In the drawings, illustratin the application of my invention in one fbrm,*l igure 1 represents a sectional elevation of my invention showing only the delivery rolls of an envelop sealing machine. Fig. 2 is a plan view of the parts shown in Fig. 1 with some parts broken away. Figs. 3 and 4 are partial views similar to Fig. 1, showing the parts in different positions. Figs. 5 and 6 are views of details.

A frame bar 10 is secured to any suitable supporting member (not shown) of the machine with which my packer is employed,

and the frame member 10 carries a series of horizontal rods 11 properly spaced apart and secured together at their outer ends by a bar 12 which comes below the plane of E the bars 11. To the ends of the bar 12 is Specification of Letters Patent.

PatentedFeb. as, 19115.

Application filed July 9, 1913. Serial No. 778,231.

pivotally secured a yoke member 12 to -Which is secured a series of horizontal bars 11', the horizontal bars 11' coming above crossbar 12 while yoke member 12 comes below the bars 11, and the outer'ends of bars 11 being secured to'a circular crossbar 12". The bars 11f are, therefore, capable of oscillating about the crossbar 12 and are held in horizontal position by engagement with said crossbar and engagement of the yoke member 12 with the bars 11. At suitable distances apart are posts 13, as shown in Fig. 6, said posts being surrounded by the tubular hubs 14 of a pair of side guides 15 and 16 which may be formed of sheet metal and are provided with shoulder portions 17 and curved portions extending outwardly from the said shoulder portions, as shown. Springs 18 surrounding the posts 13 normally tend to force said side guides inwardly or toward one another. Nuts 19 on the end of posts 13 hold the guides 15 and 16 in the desired position and permit adjustment thereof, stops 20 on the framepiece 10 operating to limit the inward movement of said guides.

A block 21 having a beveled face 22 is mounted to slide upon the bars 11 and 11,

being secured to the bars 11 by means of a plurality of wire loops 23 secured to the underside of said block and having the sides thereof extending parallel with the bottom of the block 21 and the curved portion extending below a wire 11', as clearly shown in Figs. 2 and 5. This permits the block when it reaches the crossbar 12", on the ends of rods 11, to swing over saidcrossbar into the position shown in Fig. 5 and permit discharge of envelops or letters of the stack from the end thereof in case the operator. shall not have noticed that the stack has become extended to the end of the supporting rods 11.

The envelops 24 are shown'as being delivered from the sealing rollers 25 vertically with respect to the plane of supporting rods 1.1 and 11' and in front of the slidingblock 21. A rock shaft 26 is journaled in brack ets 27 extending from frame member 10, and'has thereon an arm 28 pivotally conne cted to a link or pitman 29 which is reciprocated by means connected with the machine, not shown, and thereby oscillates shaft 26 and pusher bars 30 carried thereby in timed relation with the feed of the envelops or cards 24. Thepusher bars 30 will be of spring material'and may, as shown in Figs. 1, 3 and 4, be provided with an angularly disposed portion 31.

J ournaled in brackets 32 connected with frame members, not shown, is a rock shaft 33 havingadjustably secured thereon spring fingers 34 provided with angularly disposed fingers 35 adapted to extend between pairs ofsupporting bars 11 and pairs of pusher members 30. Spring 36, secured at one end of a lug 37 on bracket 32 and at the other end to an arm 38'fast on rock shaft 33, normally holds the members 34 in contact with the frame crossbar 10 and the fingers 35in the position shown in Fig. 1, in which said fingers form in respectio the pusher members a V-shaped receptacle for the lower.

edges of the envelops 24: as they come from rollers 25.

In 'operation'the bar 29 will immediately after an envelop 24 has been deposited between pusher members 30 and retaining members be reciprocated so. as to turn rock'shaft'26 and oscillate pusher members forwardly along supporting rods 11, as indicated in Figs. 3 and 4. The faces of the pusher members30 are thus caused to engage the backs of the envelops 24 and to move the same along the supporting rods 11. The lower edge of the envelop 24 engaging the angularlv disposed spring fingers 35 will, as the envelop, is moved, forcesaid sprin 'fin ers downward-l as indicated in Fig. 3, until such edge passes the end of the finger, when the spring fingers 35 will spring back into position behind the envelop 24 which has just been moved to the;

stack. \Vhen the pusher members 30 are returned-by reverse reciprocation of pitman 29, the fingers 35 will be in position to engage and restrain the envelops of the stack from following said pusher fingers on' their return to position for receiving another envelop.

The simplicity of my invention will be apparent. It is absolutely accurate in use and cannot fail to move an envelop and leave it in the stack. The block 21 is of sufficient weight andengages the bars 11 and 11' both directly and through the loop members23 with suflicient friction so that a compact stack is formed and yet the pusher bars 30 may move the block '21 ahead as such stack is completed. The. method of connection of the block 21 with the supporting rods 11 is such as to absolutely prevent any danger of clogging from overfeeding the stack, whilethe double, hinged arrangement of supporting rods permits an extended platform to be conveniently provided because it mav be folded one part upon the other for shipment. or when the machine is .not in use.

Furthermore, the crossbar 12 by its engagement with the securing mem- -bers'23 limits rearward movement of the .head block along the wires, said connectors thereby being fo ced under the crossbar to cause the'head block to turn over and release the stack when the same has been extended to the end of the supporting wires.

' 2. A packer comprising a supporting memberconsisting of a grid of wires. an extension Tld of wires nivotally connected with the first named grid. means for holding said extension wires in the plane ofthe first wires.'a head block slidable along said wires and means for moving envelons along the supporting wires and against the head block to form a stack.

In testimony whereof I aflix my signature in presence of two witnesses.
